A water salute
occurs for ceremonial purposes when
travels under plumes
expelled by two or more fire fighting vehicles.
At an airport, typically an even number of vehicles will line up
perpendicular on the sides of the taxiway
, and the plumes of water will
form a series of arches. Symbolically the procession would look
similar to a bridal party walking under a wedding arch or the Arch
of Sabres at a military wedding.
Water salutes are also used for ships and other watercraft, with
water being delivered by fireboats
Water salutes have been used to mark the retirement of a senior
pilot, air traffic controller or the first or last flight of an
airline to an airport, or for other notable events. When the Concorde flew its last flight from John F. Kennedy
International Airport blue, white and red
coloured plumes were used.
